The book describes the basics of the course "Processes and devices of chemical technology," read in chemical-technological universities. The book contains the following sections: hydraulics and hydrodynamic processes (movement of liquids, compression of gases, separation of gaseous and liquid heterogeneous systems, mixing), heat transfer and thermal processes (heating, cooling and condensation, evaporation), mass transfer and diffusion processes (sorption methods of gas separation, liquid distillation, extraction, crystallization and drying), refrigeration processes (cooling to low temperatures and deep cooling) and mechanical processes (grinding, screening and dosing of solid materials).
